LOL--Ya, the Blawater is the complete IDPA package all in one, nice, tidy box.
You don't see a lot of Sigs in USPSA or IDPA, and I don't know why. They can have a nice trigger, the capacity is decent...They're heavy, but they're accurate. I reckon that long reset has something to do with it.
My buddy with the X5s sold them both. He's now shooting--unbelieveably--a GLOCK 34 in Production and is waiting for a Bedel Custom 2011 for Limited. I don't claim to understand why, but that's what he did, custom made basepads and all.
My original advice still stands--get the software down pat, and then work on the hardware.
